Research Tools: California Pesticide Use Summaries

UC IPM developed this database from data from the California Department of Pesticide Regulation. The database includes summaries of pesticides used on California crops datailed by commodity, pesticide, county, and month. The database has no information about a pesticide or its label.

Unit of Measure Changes Made by UC IPM

To simplify summaries, UC IPM combined areas, volumes, and weights representing amounts treated and planted. In general "square feet" were converted to "acres," then combined with other reported "acres"; "cubic feet" were changed to "thousands of cubic feet," then combined with other reported "thousands of cubic feet"; "pounds" were converted to "tons," then combined with other reported "tons."


Codes Used in the Following Tables


CDPR Pesticide Use Codes

A = Acres
S = Square feet
K = Thousand cubic feet
C = Cubic feet
T = Tons
P = Pounds
U = Miscellaneous units (e.g., number of tractors, trees, bins, etc.)
_ = blank or null

UC IPM Summaries Codes

A = Acres
K = Thousands of cubic feet
T = Tons (short)
X = Mixed or unknown units
O = Other than production agriculture (structural, rights-of-way, etc.)





Areas were changed to A (Acres)
A = S (Square feet) divided by 43560
